答案选C
Do you remember where you bought the TV set?这句话是对的,但是刚刚那道题不能变成do you think where he bought the TVset
do you think 就是所谓的插入语.插入语的概念是插入句中的一个短语,但是对句子本身不会造成任何影响,像刚刚题目中所说的那句话,可以这样断句 where,do you think,did he buy the TV set?do you think 就直接去掉,这样句子结构就简单明了了.
再举个插入语的例子给你吧,
The spicy food,in my opinion,is really delicious.In my opinion 是插入语,可以不看.
